GATE.

SPECIFICATION forming part of Letters Patent No. 351,141, dated Gotober 19, 1886.

Application filed June 18, 1886.

T0 aZZ whom it may concern:

Be it known that I, GEORGE W. WALTEns, of Deer Lodge, in the county of Deer Lodge and Territory of Montana, have invented a new and Improved Gate, of which the following is a full, clear, and exact description.

My invention relates to gates of that class which are lifted and slid across the roadway.

and are operated by hinged lil'ting-bars,which in turn are operated by pulling on cords attached to overhead levers to which the gate lifting bars are connected; and the invention .in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my improved gate, partly broken away, and shows the gate closed in full lines and open in dotted lines. Fig. 2 is a plan view of the gate-frame and gate, the gate being shown open. Fig. 3 is a detail perspective view of parts of the gate operating mechanism, and Fig. 4 is a detail sectional view of parts of the gate on the line x :0 in Fig. 1.

To a heavy sill-timber, A, are secured the lower ends of an outer broad post, 13, and two inner smaller posts, 0 O, which latter posts are connected by a crossbar, D, to which and the upper end of the post 13 ahead-bcam, E, is fixed. Diagonally-ranging braces cstrengthen the head portion of the gate-frame. A crosssill timber, A, is let into the under side of the sill A, and is stayed to the opposite posts 0 G by inclined braces a a, whereby lateral stiffness is given the gateframe.

The outer bar or upright, f, of the gate proper, E, extends upward, and at its forked extremity carries a roller, g, which runs on a rod, G, fastened at opposite ends in the post and bar BDof the gate-i'raine. The body part Serial No. 203,544. (Model) of the gate 'Fmay have any approved construction. It is shown madeof end and center uprights, rails, and diagonal braces, and the lower rail, f, projects at opposite ends of the gate to enter a slot, b, made in the outer post, B, and to stand between blocks 0 c, fixed to the opposing faces of the inner posts, C 0, whereby the gate is steadied laterally at the bottom.

Lifting bars or levers H H are strongly hinged at their lower ends, as at h, to a crossbar or block, I, fixed to the sill A, and range upward, one at each side of the gate F, and are rigidly connected at their tops above the upper rail of the gate bya block, H, in which is fastened an eyebolt, J, the eye of which is linked to the eye of a similar bolt, K, fastened in the gate-rail]? \Vhen the gate is closed, these bars H H extend outward diagonally and fit between the beveled upper ends of the postblocks 0 c, as shown in Fig. 4, thereby aiding the outer bar, 7, of the gate,which incloses the guide-rod G, in preventing a lateral play of the upper part of the gate F. Short posts or pins L L are set into the sill A or into a timber, a fixed thereto, so as to stand one at each side of the lower rail of the closed gate and serve as guides to the gate as it is being opened or closed. The gate when closed rests upon a buffer, Z, and when open rests upon a buffer, Z. Said buffers are shown'fixed to the sill A, and may be made of rubber or other suitable ma terial to deadcn the noise and relieve the shocks of the fall of the gate.

In opposite ends of the gateframe bar D there are fixed eyebolts m m, to which are fulcru med, by eye bolts m m, fixed in them, the gate-operating levers M M, the outer'ends of which extend a sufficient distance along the roadway,at opposite sides of the gate F,to allow pull-cords m on the levers to be drawn upon by a person on horseback orin a vehicle for opening and closing the gate without dismounting or alighting. The inner or back ends of the levers are crossed and bolted together at m. tached the upper end of a rod, N, the lower end, of which is connected loosely by an eye, 9/, with the cranked portion 0 of a trip-arm, O, which is journaled at one side of the crank 0 in a metal yoke, I, bolted by its earsp to one To one of the levers there is at- 5 of the gate-lifting levers H, and at the other side ofthe crank in said lever H,0r, preferably, in a metal plate, R, fastened to the lever, there are formed-stops r r, against which the crank 0 strikes to limit the throw of the trip-arm in either direction. The stem 0 of the trip-arm 0 extends beyond the axis of the arm and about in the plane of the arm-crank 0 for a sufficient distance to strike either of two pins, S T, which are fixed inahorizontal bar, U, supported at opposite ends by one of the gate frame-posts O and by a short post, V, fixed to the sill A.

The operation is as follows: We will suppose the gate is closed, as in Fig. 1. The arm 0 then stands in the inclined position shown, and the crank 0 of the arm will be swung outward-against the stop 1* 011 the lifting-bar H. Should either of the cords m be pulled to operate the levers M M and draw the rod N upward, the lower end or eye, n, of the rod will draw on the cross piece or bar of the crank 0, which, by actionon the stop 1", will swing the lifting-bars H over on the hinges h, and thereby lift the back end of the gate F and partly open the gate, the roller 9 meanwhile supporting the forward end of the gate from the rod G and relieving the bars H of about half the weight of the gate, thereby making it quite easy for a person to operate the gate, as acomparatively light pull only is required on the cord m. As the gate is thrown past its dead-center of movement by the pull on the lever, the pull-cord is slackened or released and-the weight and momentum of the gate will carry it to full open position. About the time the gate passes its center of movement the stem 0 of the trip-arm 0 will strike the pin T to reverse the crank 0 and carry its wrist backward until the crank strikes the stop 0'' on the liftingbar H about the time the back end of the gate swings down onto buffer Z, leaving the crank in position for the next pull on it to close the gate. To close the gate,one of the lever-cords M. will be pulled and the bars H will be raised with the back end of the gate by lift of the trip-arm crank o on the stop 1" of the liftingbar, and as the gate passes the center by its momentum, the stem 0 of the trip-arm will strike the pin S, again reversing the position of the-crank and swinging it forward or outward until the crank again strikes the stop 1' as the gate closes, to bring the crank-arm to the required position for the next pull on it by the lever to open the gate. In closing the gate the roller 9 and guide-rod G relieve the lifting-bars and the operator of the weight of the gate, as when opening the gate as above described.

The rigid connection of the ends of the liftingbarsH H, by means of the block H, bolted securely to and between the bars, allows operation of the gate by a single rod, N, connected toone of the bars H and to the levers M, and also prevents any side strain on the gate in opening and closing it, and the eyebolt-connections of the gate and lifting-bars allow lifting and swinging of the back end of the gate with very little friction.

The guidepins L L offer little or no obstruction to travel over the roadway which the gateframe spans. The uprights of the frame may be set firmly into the ground and the sills A A be dispensed with; but when the sills are used they will usually be covered with earth, leav ing the top of the sill-timber a about level with the ground surface.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with the gate-frame, of a horizontal guiderod held thereby, the gate proper having an outer bar hung upon the guide-rod, and lifting-bars hinged at their lower ends to a ground-supportand connected at their upper ends with the gate, and means for operating said bars, substantially as shown and described, whereby as the liftingbars and gate are operated part of the weight of the gate will be borne by the overhead guide-rod, as set forth.

2. The combination, with the grate-frame, a horizontal rod, G, thereon, the gate F, having an outer bar, f, hung on rod G, lifting-barsH H, hinged at h to a ground support and connected rigidly at their tops by ablock, H, and

suitable fastenings, overhead operating-levers a trip-arm, 0, formed with a crank, 0, and I stem 0, and journaled on the bar H, and trippins S T, positioned for contact of the trip-arm with them, substantially as described, for the purposes set forth.

In combination, the gate F, a lifting-bar, as at H, hinged to a ground-support and attached at its upper end to the gate, and provided with stops 9* r, a trip-arm, 0, having a. crank, 0, and stem 0, and journaled on the bar H, trip-pins S T, positioned for contact of the arm 0 with them, and a pull-rod, N, connected to the cross-bar of the crank 0 and to operating-levers, substantially as described,
